Abstract
A method for communicating using a hybrid vehicle communications network including a combination of wired and wireless electronic control units (ECUs) and wired and wireless peripherals. The network includes a plurality of ECUs that include a plurality of wireless ECUs. The network also includes a plurality of peripheral devices, where one or more of the peripheral devices receive commands from one or more of the ECUs and one or more of the peripheral devices provide signals to the ECUs, and where the plurality of peripherals include at least one wireless peripheral. Wireless transmission signals transmitted from one of the wireless peripherals is received by all of the wireless ECUs. The method performs an arbitration process where a message provided from one of the wireless ECUs is placed on a communications backbone based on a quality of the transmission signal from the wireless peripheral.
